'Silverband' notes - Uses: Water gardens

Won't JI likely not survive a below freezing winter with their roots submerged?
Japanese Iris (Iris ensata 'Silverband')

Correct you are, would you like to do an update and specify this? It's the crown that can't freeze over. Good catch.

I'll take care of it Polly. I hope folk don't treat them like "water Iris" as I see sites selling/listing them that way.

Edit
Polly, After re-reading your "Cultivation Of Japanese, Bog, Water and Species Beardless Irises" I realize non of them want their crowns frozen. Correct?

Thanks Evan. Hopefully they will see your comments!
